HP has revealed faults with 38 different models in its slimline PC range, sparking speculation that Nvidia's faulty GPU problems have spread beyond laptops. HP's official statement says the problems are 'attributable to the computer's motherboard" and that affected machines 'may not boot or may not display video' — the same kind of terminology used to describe the previous faults with laptop GPUs. Both HP and Nvidia have declined to comment. But in a filing to the US Securities and Exchange Commission (SEC) earlier this year, Nvidia admitted 'there can be no assurance that we will not discover defects in other MCP or GPU products.'
